We had a very pleasant stay at Jam's place. The room was very clean and comfortable and the house is beautiful and big. They provide very good breakfast and also help tourists plan their visits. It is in the heart of the city and very close to the most popular places to visit in Bangkok like Khao San road, Grand Palace, etc.
The path to access the house from the main street is narrow and dull so make sure that it does not make you uncomfortable.
